Abstract

The present invention is mounted on the hull and the hull, the stack and flat cross-sectional shape for discharging the exhaust gas generated during operation to the outside corresponding to the stack is provided at the top of the stack, the air from the front to the rear to the front and rear respectively Provided is a vessel comprising a guide portion formed with one or a plurality of flow holes to guide the flow.
Therefore, it is possible to prevent the inflow of smoke into the ship by the exhaust gas within the limited height of the stack, and to prevent contamination of the cargo area behind the exhaust pipe, and to exhaust the air through the guide provided at the top of the stack. By improving the gas flow and sending the exhaust gas away, it is possible to reduce the smoke concentration and smoke nuisance on the ship.

Description

Ship {Ship}

The present invention relates to a ship, and more particularly, to a ship capable of improving the flow of exhaust gas discharged from the stack and further spreading the exhaust gas to prevent contamination by the exhaust gas.

In general, ships sail to their destinations with various structures such as funnels, accommodation, and cargo on their hulls, and these ships use main fuel and auxiliary engines in the engine room. After combustion, internal combustion engines such as boilers and external combustion engines exhaust exhaust gases through exhaust pipes.

On the other hand, the exhaust gases are high in temperature, have a lot of harmful components, and have a black color, so that various navigation communication equipments located around the exhaust pipe are damaged by heat or soot, and the cargo area is not only contaminated by smoke. In addition, there was a problem that the problem that threatens the health of workers or crew members re-enter the machinery space.

In addition, the conventional ship, there is a problem that the harmful substances contained in the exhaust gas is not smoothly discharged to the outside air while the vortex is generated behind the stack and adversely affect the hull. Thus, a method for solving the above problems may be a method of increasing the exhaust pipe as much as possible, but in this case, the height due to the structural problems such as interference of the radar mast, air draft, etc. There is a problem that this solution is not so limited.

In other words, the conventional ships do not exhaust the exhaust gas smoothly to the atmosphere, so that the exhaust gas is re-introduced into the ship, not only to contaminate and destroy the cargo, equipment and accommodation of the hull, but also to the health of the crew There was a problem that adversely affects.

The present invention is to provide a vessel that can smoothly flow the exhaust gas to the outside while inducing the ship to prevent damage and contamination of the hull, the structure mounted on the hull, and provide a comfortable environment for workers. There is this.

According to the present invention, a stack and a flat cross-sectional shape mounted on the hull and the hull and discharging exhaust gas generated during operation to the outside correspond to the stack and are provided at the upper end of the stack, and the air is forward and rear respectively. Provides a vessel comprising a guide portion formed with one or a plurality of flow holes to guide to flow backward in the.

The flow hole may include a plurality of inflow holes formed in front of the guide part and a plurality of outflow holes formed in the rear of the guide part, and the inflow hole and the outflow hole may be located to correspond to each other.

In addition, each of the inflow hole and the outflow hole may be formed in the same shape with the same size.

The guide part may be integrally formed with the stack.

The stack may further include a frame mounted on the hull and having an exhaust air opening on the rear surface thereof, and one or a plurality of exhaust pipes accommodated in the frame and exhausting the exhaust gas into the atmosphere. Include.

The ship according to the present invention provides the following effects.

First, it is possible to prevent the inflow of smoke into the ship by the exhaust gas within the limited height of the stack.

Second, it is possible to prevent contamination of the cargo area behind the exhaust pipe.

Third, it is possible to improve the flow of the exhaust gas through the guide portion provided at the upper end of the stack, and to send the exhaust gas far, thereby reducing the smoke concentration and smoke pollution on the ship.

Fourth, by allowing the air from the upper front to the rear of the stack to flow through the guide portion, vortex generation behind the stack can be reduced, and exhaust gas can be smoothly discharged.

1 is a view showing a ship according to an embodiment of the present invention.
FIG. 2 is a perspective view illustrating the stack of FIG. 1. FIG.
3 is a cross-sectional view illustrating the structure of a stack of FIG. 1.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing a ship according to an embodiment of the present invention, Figure 2 is a perspective view showing the stack of Figure 1, Figure 3 is a cross-sectional view showing the stack of FIG.

First, referring to FIG. 1, a ship 400 according to an embodiment of the present invention includes a hull 100, a stack 200, and a guide part 300.

The hull 100 is a structure constituting the vessel 400, which is similar to a known hull, so a detailed description thereof will be omitted, and also the accommodation port 110 and the cargo area 120 disposed on the hull 100 Detailed description thereof will be omitted. Only the characteristic parts of this embodiment will be described below.

The stack 200 is mounted on the hull 100 and serves to discharge the exhaust gas generated during operation to the outside, and includes a frame 210 and an exhaust pipe 220.

The frame 210 is mounted on the hull 100 and the upper side is opened to accommodate the exhaust pipe 220 therein, and an excess air opening 211 is formed at a rear side thereof, and the outlet 211 is formed. The bet is discharged from the engine room to outside.

The exhaust pipe 220 is connected to an internal combustion engine or an external combustion engine in an engine room to exhaust the exhaust gas generated from the engines.

The guide part 300 is provided in the upper end of the stack 200, the flat cross-sectional shape corresponds to the flat cross-sectional shape of the upper end of the stack 200 has an open structure. In addition, the guide part 300 is formed with one or a plurality of flow holes 310 to flow the air from the front to the rear during operation.

Here, the flow hole 310, one or a plurality of inlet holes 311 formed in front of the guide portion 300, and one or a plurality of outlet holes formed in the rear of the guide portion 300 ( 312).

At this time, each of the inlet hole 311 and the outlet hole 312 is located to correspond to each other so that air flows smoothly from the front to the back. Further, the inlet hole 311 and the outlet hole 312 may be formed in the same shape of the same size, but is not limited thereto.

On the other hand, the guide part 300 may be formed integrally with the stack 200.

As described above, the ship 400 according to the present embodiment prevents smoke from reintroducing into the ship within the limited height of the stack 200 and prevents contamination due to smoke of the cargo area behind the exhaust pipe 220. On the other hand, it is provided with the guide portion 300 to guide the flow of air to flow smoothly from the front to the back to exhaust the exhaust gas to the atmosphere, it is possible to prevent damage to the electrical equipment, the concentration of smoke on the ship It can reduce the smoke concentration and smoke nuisance.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
